CDC Streptococcus Laboratory
CDC’s Streptococcus Laboratory provides support for active population-based surveillance for invasive streptococcal disease, primarily caused by groups A and B streptococci and Streptococcus pneumoniae. It supports state and local health departments in the United States to characterize streptococcal isolates and is active in many international collaborations. The laboratory is a reference center for the identification and characterization of streptococci and other Gram-positive catalase-negative cocci.
